I do something this

<zscript>

void reset(){
username.setValue("");
password.setValue("");
con_password.setValue("");
}

void register(){
String errorMsg = "";
if(username.getValue()==null || username.getValue().trim().equals("")){
errorMsg += "Username cannot be empty!\n";
}

/*if(password.getValue()==null || password.getValue().trim().equals("")){
errorMsg += "Password cannot be empty!\n";
}else*/ if(!password.getValue().equals(con_password.getValue())){
errorMsg += "Passwords do not match!\n";
}

if(!errorMsg.equals("")){
Messagebox.show(errorMsg,"Error",Messagebox.OK,Messagebox.ERROR);
}else {
registerWnd.onRegister();
}
}
</zscript>
<grid>
<zscript><![CDATA[
Constraint ctt = new Constraint() {
public void validate(Component comp, Object value) throws WrongValueException {
org.zkoss.zul.Calendar oggi=new Calendar();

}


}
